Materials - Data Set Description

Data set overview:

  • 14481 different genes

  • 63 samples

    • 9 with T2D

    • 54 controls

Descriptive statistics:

  • Similar mean gene expression across groups

  • Overall low mean expression levels

  • Slightly right-skewed distribution

  • => Investigate significant difference of genes between the groups

Materials - Wrangling

Frederik

Methods - Median Expression Differences

  • Goal: Identify genes with largest expression differences between T2D and control
  • Approach:
    • Compute median expression per gene for T2D and control samples
    • Calculate absolute differences between groups per gene
  • Visualization:
    • Plot 30 genes with the most different expressions
    • Bar plot and boxplots

Discussion / Conclusion

1) Difference in two methods

2) Sum up which genes are found by the analysis

3) does they support the litterature? uniprot…
